I don't remember for sure, but can the 95 model be scanned by an OBDII reader? If so, that may help in pin-point the issue, as the 11 code is kinda broad.

Check the connectors and wires on both, the cam sensor and the crank sensor, to make sure they're not corroded, cracked, or broken some how. When the wires/metal connectors heat up, they expand, and can sometimes make better connections than when cold.
